People love their Smartphones – until they run out of power. Usually at the worst possible time: Traveling. Outdoors. During a blackout. Or having car trouble. With the TravelCard, you always have reserve power available, in your wallet. It’s the exact size of a credit card, only 3/16″ (4.77mm) thick and weighs just 2 oz. (56.7g). You can say goodbye to annoying cables and bulky portable chargers.
